Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Development of a fast and convenient method for the isolation of triterpene saponins from Actaea racemosa by high-speed countercurrent chromatography coupled with evaporative light scattering detection.[Pubmed:
19847744 ]
In the present work, a fast and simple method for the separation and purification of triterpene saponins from Actaea racemosa was successfully established.
METHODS AND RESULTS:
Accelerated solvent extraction was used for defatting and extracting of the subaerial parts, giving a triterpene enriched crude extract. Size exclusion chromatography was used to separate actein and 23-epi-26-deoxyactein from other triterpenoids, which were collected in a third fraction. This most complex third fraction was applied to high-speed countercurrent chromatography, a well-established technique for the separation of saponins. Separation parameters were first optimized on an analytical level, using a hyphenated HSCCC-ELSD setup, before the system was scaled up to preparative size. The resulting two-phase solvent system, consisting of N-hexane-acetone-ethyl acetate-2-propanol-ethanol-water (3.5 : 1 : 2 : 1 : 0.5 : 2, v/v/v/v/v/v), enabled the isolation of 23-O-acetylshengmanol-3-O- beta-D-xylopyranoside (17.4 mg), Cimiracemoside D (19.5 mg), 25-O-acetylcimigenol-3-O-beta-D-xylopyranoside (7.1 mg) and the aglycone cimigenol (5.9 mg). Purity of the isolated substances was 96.8 %, 96.2 %, 97.9 %, and 98.4 %, respectively.
CONCLUSIONS:
The same method was suitable for the purification of actein and 23-epi-26-deoxyactein, with purities of 97.0 % and 98.3 %.
